A vaccine produces its effects by?
A vaccine works by causing the body's immune system to create antibodies against itself. Ideally, the body has such a strong response to the vaccine that it creates memory B cells, which can turn themselves on if the animal is ever exposed to the disease and create a large number of antibodies very quickly.
To inject a vaccine is to?
To inject a vaccine is to introduce a small amount of the vaccine, usually through a needle, into the body. This helps stimulate the immune system to produce antibodies and create a defense against the specific disease targeted by the vaccine.
Why does a vaccine have to be a specially prepared version of a disease pathogen?
A vaccine is a special version of an antigen the gives you immunity against a disease. A vaccine is a weakened form of disease which helps your immune system create antibodies to fight it off so later if you ever get that certain disease again your body would recognize it and create antibodies to fight against it before it gets too serious.
Why doesn't immunisation always work?
because the immune system may not be strong enough to create antibodies also when a vaccine is used it could of weakened the immune system ...
Injecting a person with a vaccine so the body will create antibodies against a disease is an example of which type of immunity?
Injecting a person with a vaccine to stimulate the body to produce antibodies against a disease is an example of active immunity. This type of immunity occurs when the immune system is exposed to a harmless form of the pathogen, prompting it to generate a specific immune response. Unlike passive immunity, where antibodies are transferred from another source, active immunity involves the individual's own immune system actively producing antibodies.
What does a vaccine produce?
When a vaccine is given to an animal, the animal's immune system produces antibodies to fight off the disease. This way, if the animal is ever infected by the disease it was vaccinated against, the animal will either not get sick or not get as sick.
It is known that if a person develops cow pox and recovers and then is exposed to smallpox and he or she is less likely to develop smallpox why?
This is because the two types of pox are related. Someone exposed to cowpox will develop antibodies to the cowpox. These antibodies will help fight against small pox. This phenomenon was observed by Edward Jenner, who used it to create a smallpox vaccine. (The word "vaccine" is related to the Latin word for "cow".)
What are blood groups and what is their importance?
Blood type is determined by antibodies and antigens present in red blood cells antibodies A and B for blood group A and B, when there's no antibodies it is group AB, when both antibodies A and B is present then it is group O
What causes a vaccine to prevent a certain disease?
a vaccination is a dead or deactivated virus. the body treats the vaccine as a threat to the body, so it fights the disease. it leaves you with memory T (killer cells) and B (cells that create antibodies). when the actual disease comes, the memory B cells make antibodies that stick to the disease cells antigens, and the memory T cells kill the disease, to end the disease before it can start.
What are deactivated viruses used to create antibodies?
Deactivated viruses, also known as inactivated or killed viruses, are used in vaccines to stimulate an immune response without causing disease. When introduced into the body, these viruses cannot replicate but still elicit an immune response, prompting the production of antibodies. This prepares the immune system to recognize and fight the actual virus if encountered in the future. Examples of vaccines using deactivated viruses include the polio vaccine and the hepatitis A vaccine.
The some hive cells mutate making it difficult to produce a vaccine?
The mutation of some hive cells can lead to changes in the surface proteins that the immune system recognizes, making it difficult to create a vaccine that effectively targets these mutated cells. This can complicate vaccine development and require additional research to create an effective vaccine against the mutated hive cells.
Why cant you get measles more than once?
In rare cases a person can. Generally though, it is a one time deal. Measles are caused by a virus. After a healthy body is exposed to a virus it will create an anti-virus to fight it. When the person is recovered from the illness they will be immune. This is also how the measles vaccine works. The vaccine introduces a small amount of the virus for the body to create immunity to.
